以往要想育出水稻的旱育壮秧来,就得选用肥沃的耕层土壤作为育秧床土。据测算,种植1亩水稻,每年需要育秧床土150公斤。怎样才能更好地在不破坏农田土壤资源的情况下,解决好育苗床土的难题呢?黑龙江省八五三农场的科技人员,利用生物技术发酵稻壳制造有机肥,通过与粉碎后的稻壳进行合理搭配,人工模拟土壤,进行水稻育秧,达到了水、肥、气、热相互协调的育秧效果。经过400多组的试验,成功开发出利用稻壳进行水稻育秧的技术。水稻稻壳育秧,是采用现代人工模拟土壤方法,以稻壳为基质,替代床土的一种新的育秧技术。
In the past to give birth to paddy rice nursery seedlings, you have to use fertile top soil as seedling bed soil. It is estimated that planting 1 mu of rice, annual need to bed seedling 150 kg. How can we solve the problem of nursery beds better without destroying farmland soil resources? Science and technology personnel at the “853” farm of Heilongjiang Province use organic fermented rice husk to make organic fertilizer, Shell with a reasonable mix of artificial soil simulation, rice seedlings, reached water, fertilizer, gas, heat and mutual coordination of the effect of raising seedlings. After more than 400 sets of experiments, the successful development of rice husk rice seedling technology. Rice husk nursery seedlings, is the use of modern artificial soil simulation methods to rice husk as a substrate, instead of bed soil a new seedling technology.
